Abstract:
A low-, medium-, or high-voltage voltage switchgear with a circuit breaker or circuit breakers is disclosed which can switch electrical equipment. To protect the switchgear, and the circuit breakers in the switchgear against so called spot welding under vacuum atmosphere, such as during a closing operation of a switchgear used, for example, for switching capacitive or inductive equipment or inductive or capacitive current network an inrush current limiter is placed electrically in line or in series with the current path of the circuit breaker.
